Royal Canadian Legion's Periodical

The vividity of the colours (similar to the quality in the recent colourised film) suggests that the photo has been tweaked and tidied up recently.

Regarding an original colour photo but unless someone more in the know can clarify otherwise my understanding is that all early colour photos were in fact black and white with the colours added later. Certainly that's the case with colour postcards from the late 19th early 20th c. I may be wrong though?

While there was a rudimentary colour photography process about this time, it's pretty rare. Colour photographs don't become commonplace for candid/home use until Kodachome is invented in the 30's. Not really popular until after the next war. That's why most WW2 era photos are B&W.
It was common to hand colour a photo after printing. The colours are usually very vivid. This photo is a bit puzzling , however. The tartans are well done- it'd be hard to do that by hand for all those kilts. Suggests computer enhancement not hand done. On the other hand, note that the flashes are not uniform in shade. The blue of the shoulder patches really stand out . Perhaps that's our hint. Did the 13 RHC use blue shoulder patches?
